. l KITE" Fi1ed llay 28, 1949 2 Sheets-Sheet 2 FHCME INVENTOR. FRED H. OHLAND ATTORNEYS Patented Aug. 22, 1950 .This invention relates to improven'ients in kites.

It isanf'object ofthe invention to provideva kiteconstruction whichv is simple and-{cheapx-toA manufacture and which 'at the same time is: sturdily constructed, so that it will withstand' relatively 4high `winds and will greatly resist breakageY in the event it should dive to the I ground.

.-Another obiect ofthe invention is to provide a kite construction which is suppliedwith a bridle cord or cords so arranged that the lead cord or cords will be connected thereto with the bridle cordheld at the proper angle to the surface-of the-kite. i Y I Another object of the invention is to provide a kite'withV simple but eflicient means for steering thefsame,l and for reeling andunreelingthe lead cord. y -I I The `above and other objects ,and advantages of the inventionwill morefu'lly appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same parts through,- out the views, and, in which:

Fig.A l is ai perspective viewof' the embodiment of the-invention showing the 'kite and? control and winding4 reel in operativepositions.

Fig. 3 is a side elevational View.

Fig. 4 is an end view.

Fig. 5 is a perspective view of the kite showing one form of bridle and lead cord tying means.

Fig. 6 is an enlarged fragmentary detail of the tying means shown in Fig. 5.

Fig. 7 is an enlarged fragmentary perspective of the cover sheet securing means.

Fig. 8 is a View similar to Fig. 7 with a portion of the cover sheet disconnected from the frame.

Fig. 9 is an enlarged plan view of another form of bridle and lead cord tying means, the cords being shown in dotted lines, and

Fig. 10 is an enlarged longitudinal sectional view through the control and winding drum.

The kite has a frame including an upright II and a cross-member I2, these being suitably connected as by a small brad I3.

Fig. '7 shows one end of the cross-member I3 and it is provided with a notch or slot I4 cut in from'its end. This notch is preferably formed on each end of the upright and the cross-piece.

The kite has a cover sheet vI5 which ordinarily is of paper or of other suitable material. The cover sheet is generally of polygonal shape and its edges having reinforcing strips I6 secured I2A Claims.- (o1. 244-153) thereto in any suitable manner, such as by an adhesive. At each corner of the cover sheet I5 theedge. reinforcing strips I6 overlap as shown in` Figs. 7 and 8,. and anaperture Il is formedthrough A'this reinforced and overlapped corner.

The apertures` Il in thecorners of the` cover sheetand the. reinforcing strips are `adapted to receive a 'rubber binder I8 therethrough.. as indicated in. Fig. 8', leaving a loop I9` at each side of'thesheet I5. These loops are placedin `the notchesv I4 and in the. ends. of the frame pieces,

(as, shown in Fig. ,7, so that the cover sheet-l5 I51 is: stretchedY fairly tightly over theframeryet itv willgivewhen the kite hits the ground or some other solid object, and it hasbeen found that it willvstand considerable, shock without rupturing the coversheet. I

The kite is shown with a pair of bridle cords' 2fsecuredy at spaced points to the cross-piece I2, and-a complementarypair of bridle cords -2I eX- tending. from` a lower portionof `the upright II and diverging'upwardly and outwardly and ,connecte'd with. the outer ends of the'bridle `cords as` shown in the drawing and 'extend downwardly;- to` areel construction to bedescribed -be- In Fig. 6; one form of bridle cord and lead cord tie arrangement is shown. The bridle cords 20 Vand 2I are provided'with pre-formed and permanent loops 23 and 24 respectively. The upper end of a lead cord is extended through said loops and tied to form a loop 25. The loops 23 and 24 are formed by the kite-maker on the bridle cords 20 and 2| so that when the lead cord 22 connects them together there will be a denite angle of the bridle cords 20 relative to the general plane of the cover sheet I5. As best shown in Fig. 3, the bridle cords 20 lie at right angles to the general plane of the kite and its cover sheet.

In Fig. 9 there is shown another form of tie means for the bridle cords and lead cords. This is a wire element 26 having a split loop 21 to which the lead cord 22 is tied. The other end of the tie element 26 is provided with a keyhole loop 28, which is adapted to receive the knotted ends of the bridle cords 20 and 2 I. It is preferred that the bridle'cords 20 and 2| be knotted at the factory in order to maintain the desired angular relationship mentioned in the preceding paragraph.

In Fig. 10 there is shown a reel '29 made up of cylindrical sections 30 having closed adjacent end portions 3| pivotally connected by a bolt 32 having a wing nut 33 thereon. One of the sections 30 can be rotated relative to the other and it is preferred that the wing nut 33 be tightened to the extent that the two sections 30 will have a dragging frictional contact between them, so that normally they will turn together but one can be held stationary while the other is rotated or partially rotated. l

Each of the cylindrical drum or. reel sections 30 has a pair of flanges 34 thereon and about its cylindrical wall. These anges 34 are spaced inwardly from the outer ends of the sections 30 and the lianges of each pair are spaced from each other, so that there is a reel hub section 35 between each of the flanges of a, pair. It should also be noted that the flanges of each pair diverge outwardly to facilitate winding of the lead cords 22, even though the winding drum unit may not be always held at right angles to the lead cords. The outwardly extending'portions 30a of the drum sections 30 which lie beyond the outer flanges 34 constitute hand hold portions and provide continuous and smooth drum end portions about which the hands can slide as the drum is being wound or unwound.

With a kite rigged in the manner shown, it is possible to control its flight dir-ectionally and to make it perform different maneuvers such as dips and loops by lengthening or shortening one of the lead cords 22 relative to the other. This can be done by either rotating one reel section or merely tilting the axis of the drum unit, depending upon the maneuver desired.

It has been found that bridle and lead cord arrangement such as shown and described will operate with complete success without a spreader bar between the bridles where they connect with the lead cords, thereby reducing the cost of material and the Weight of the kite.

The manner of reinforcing the edges of the cover sheet I5 and also the manner of mounting the cover sheet on the frame provide a kite which is extremely strong and resistant to shocks.

The predetermined fixed angular relationship of the bridle cords relative to the cover sheet l5 is an important feature and the tie means or connecting means for the bridle cords make the device extremely easy to set up for use.

If a single bridle and lead cord are used, the bridle cord sections will be connected from a lower portion of the upright Il to the upright and the cross-piece where they cross each other. For that purpose an aperture 36 may be provided in the upper central portion of the cover sheet l5.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.

What I claim is:

1. In a kite, a frame, a thin polygonal sheet of material approximately co-extensive with said frame, the corners of said sheet being reinforced, said reinforced corners having apertures therethrough, said frame having portions lying adjacent the corners of said sheet, and an elastic connector between said sheet corners and adjacent portions of said frame.

2. The structure in claim 1 and said frame portions adjacent the corners of said sheet being extended outwardly beyond said corners, and said elastic connector being disposed between said sheet corn-ers and outwardly extending frame portions.
